-While as above stated, the attachment is designed primarily for washingmachines and will be so described, it is obvious that it could also beused in connection with other'types of 7 machines, articles of furnitureor other kinds of'bodie's. o 'Itis one object of theinvention to providean exceptionallysimple and inexpensive, yet an 'e'llicient and reliableconstruction and arrangement of parts, for attaining the desired H ends.In the preferred constructlon, two verzoti cal guide tubes are providedfor two supplemental legs, spring means areemployed'for normally raisingthese legs, a horizontal bar extends between and is connected with saidlegs, and a'cam lever is provided for depressmg legs and bar topositionthe former for operation; Further objects are to provi 3 uniqueanchoring means for the springs which normally raise the legs, toprovide unique connections between the legs and the horizontal operatingbar therefor permitting depression of either leg more than the other ifnecessary to bring both ofthem into contact with the floor surface, andto provide unique means for mounting the cam lever and'for holdingthe'horizontal bar in operativerela-tion therewith.

c With the foregoing in view, the invention resides in the novel subjectmatter herein after described andclaimed, description being Iaccomplished by reference to the accompanying drawing.

l Fig. 1 is a side elevation partly broken away and in section.

Fig. 2 is an end view. Fig. 3is a fragmentary vertical section sub:

; stantially on line 33 of Fig. 2.

Fig. '14 is a vertical sectional view on line H of Fig. 3. c Fig. .5 isa horizontal sectional view on line a 55 of Fig. 1.

The drawing above briefly described illustrates' the preferred form ofconstruction, and while this construction will be herein specificallyexplained, it is to be understood that within the scope of the inventionas claimed, variations may be made.

The numerals 6 denote two leg-guiding tubes provided with bosses 7 forengagement with cap-screws or the like 8 by means of which the tubes maybe secured in vertical positions to a portion of a washing machine 9 orother body with which the invention is to be used. The inner sides ofthe tubes 6 are each provided between their ends with a longitudinalslot 10, and a pair of supplemental legs 11 which are slidably receivedin saidtubes, are formed with comparatively short slots 12 registeringwith said slots 10. A horizontal bar 18 has its ends passed through theslots 10 and loosely received in the slots 12 so that legs and bar areconnected for vertical movement and the angular relation between saidbar and legs may vary to some extent, permitting depression of one legto a greater extent than the other when '25- the bar 13 is depressed todownwardly project said legs. Thus, both legs may be brought solidlyagainst the floor surface even though the latter may be more or lessuneven.

Two arched spring-anchoring plates 14 are so provided, the legs of saidplates being welded or otherwise secured at 15 to the upper ends of thetubes 6, while the crown portions of said plates are disposed over saidtubes. Coiled tension springs 16 which are posi- S5 tioned in the upperportions of the tubes 6 above the legs-11, have their upper endsconnected at 17 with the crown portions of the plates 14;, while theirlower ends are welded or otherwise connected at 18 to the upperextremities of the legs, said springs thereby normally exerting theirtension to hold the legs in raised inoperative position so that the body9 may rest upon its own legs or casters. I 1 Y A cam lever 19 isprovided for acting downwardlysubstantially upon'the central" portion ofthe bar 13 for the purpose of depressing this bar and the legs 11,bringing the lower ends of the latter against thefloor sur 100 anylateral-springing of the latter.- This support is preferably of theconstruction described below.

Two relatively short -vert-ic-al bars .2l22

: are disposed at opposite sides of the bar 13 and are integrallyconnected at 'theirlower ends with each other, as seen at2 3.. Lever.19is fulcrumed at 24 between the upper prtions of, these, vertical, barsandthe upper ends. ofsaid bars are, integrally connected bya web 25disposedvat verticaledges there or; so that said bars must remain infixed relation- Thentoo, this-web forms a: stop for the lever 19when'the latter isin the idle position sh own-forinstance in Fig, 1. The

V innerbarQl is-providedwith a lateral attaching armorplate 26p,rojectin-g fro1n its upper end andprovided with bosses- 27 toengagecapscrewsor the like-28 by means of which the-entirelevera-ndabarguide is rigidly-secured tothebody 9,

It will :be seenfrom theforegcing that the invention'is rather simpleand inexpensive, yet} that: it willibe" eflicient and desirable Vvhenthe legs ll areraised, the body 9 may b'e'readilyash ifted upon theconventionalsups porti -ig :Ineans "thereof, such as casters, and

whfenlever 19 is operated to project the legs, these legs take theweight, rest solidly upon .the supportingzfloor, and thus hold the liodyagainst slippage; and against any wabbling. On account of the uniqueconnectious betweentherbarr13 and the legs 11, one or the other: 0%:these legs" may move downwardly ma greaterextentthian the: other leg,there'- bygcompensating 'for irregularities in the floor su riacex;l/Vhen the use otthe-attaclr n en t-T is no- --longer needed; it issimply necessary'to' move the lever 19'from the position of Fig. 3 tothat of Fig. 1, whereupon the body 9 again rests upon its own supportingmeans.

Attention is again invitedto the fact that while :the preferredconstructionhas been shownand specifically described, variations may:be'maderwithin the scope of the; invention-ias claimed. a
